Well technically it is not immoral (It is hard for me to write that because I know some women will take that the wrong way, and what do I really know about daughters, I have none)  But to be honest the likelihood of finding a woman in that age range that is willing to marry and parents let marry is probably very little.

The arguments is that this society (the year 2025) has not prepared, no supports women making that choice at that age.  Women will do what is standard.  They will not look different to their friends.  It is really not a discussion of morality, but a discussion of reality.

And on the flip side a majority of young men do not respect woman as they should.  I don't want to argue about this.  I just want it admitted that both men and women are imperfect.  Instead of attacking the imperfections we should try to find things to encourage each other with.

Just my two cents from paying attention to what the young woman are talking about.  It matters to me because I have sons.  My thought process is that it might be easier for my sons to pay attention to whomever God puts in their path and if the woman is not already a Traditional Catholic that she is open to converting.  My sons are probably going to have to be expert apologists (Is that the right word?).  Anyways, I digress. 

I really do have a lot of sympathy for a single, traditional man in the world.  It is not easy.  I am also afraid that it is going to get harder before it gets better.

If you are really interested, befriend their dads, because if the daughter-father relationship is good, the daughter will not do anything that disappoints her father.  Meaning that if the father dislikes you, then you have no chance with the daughter.

While I agree with most of it, I will point out that if a women really finds a man attractive she will try to lock him down, as women have a tendency to try for the best option then settle for less. Unfortunately for secular women that involves sinful behaviour which makes them unmarrigable.  It's also why most men do not respect most women, their behaviour, speech, beliefs and how they present themselves not only make them unworthy of respect but make men want to disrespect them because those things I have mentioned are disrespectful to men.

And I think a lot of people are in denial to what men want/prefer and like. Due to the century of brainwashing, the fact is a lot of modern women hate men. And it doesn't help that civil laws benefit women while are stacked against men. Finding a good secular women as a man is like sweeping a mine field without, you can easily get blown up in your face having your life ruined and everything you worked for.

It seems like this thread has become derailed.
The OP asks about an older convert marrying.
My answer is yes, same as anyone else. After prayer, seeking advice from a priest or older long time Catholic, it seems God’s Will is marriage, then pursue it.
If it’s God’s Will, you’ll find a suitable spouse. Put yourself out there. If you meet a potential, ask her out. What’s the worse that can happen?  She rolls her eyes, laughs in your face and tells you to get lost?  If that’s the case, thank God He’s answered right away that this woman isn’t for you! You wouldn’t want to marry or even befriend someone like that!  
Join activities that will put you where other Catholics will know you exist. I’m not necessarily limiting it to women. Maybe another man or married woman will know of a suitable woman and introduce you. 
You needn’t decide whether to marry or remain single. Since you’re already a single-in-the-world, work on becoming a saint. Keep an eye out for that woman, so if she’s out there, you’ll be a holier man. 
If you were mistaken about marriage, no worries. If you are working out your own salvation, God is pleased with you. Be content in whichever state you are.

I think we have lost the ability to recognize beautiful bodies without equating it to something sinful.

Exaggerated generalization.  

I think your words are harsh/cruel and not true. [...]

Reality doesn't care what you think, anonymous coward.

I think some of you have some porn addiction problems, possible molestation histories (prey and/or predatory), too much time on your hands, an underdeveloped spiritual life and, the possibility of damaged family life.

If we need to take this topic to the men's forum- let Matthew know but it is evident some of you need help.

You're projecting, and it's time for you to turn yourself in to the local authorities for your skeletons in your closet before it escalates to the point of you harming an innocent.
